Using DiscDupe 2000 Options
This section explains how to use DiscDupe 2000 options.
Using a Temporary Image
Use Temp Image allows you to save a temporary image file on your hard disk and
then write the image to your PlexWriter. The file is automatically deleted when the
duplication is completed.
You should use a temporary image file for a CD-to-CD copy if the source disc is
damaged or scratched. Use Temp Image is the safest way to copy a CD, but requires
extra time if the source disc is poor quality. Depending on the size of the source disc,
you may need up to approximately 700 MB of free space on your hard drive.
Use Temp Image also lets you use a single PlexWriter both as source and destination
drive.
Using Images
The CD to Image option creates an image of the source CD disc in a user-specified
location on your hard disk. This image is only useful for later writing to a PlexWriter
in DiscDupe 2000.
Images are particularly useful when several copies of a disc are needed or if another
duplicate of this disc will be needed at a later time. It is also extremely helpful if you
do not have a blank disc available.
The Image to CD option copies the image of your CD from your hard drive to the
PlexWriter drive.
Selecting the Speed
When speed is set to Auto, DiscDupe 2000 tests the source disc for lowest read
speed at a given point on a disc. (Read speed is affected by fingerprints, poor disc
manufacturing, scratches, etc.. It is also affected if DMA mode is not enabled on
your PC for your ATAPI CD drive.) By using the lowest encountered read speed,
DiscDupe 2000 can determine the maximum data write speed to ensure a successful
copy, trying to reduce the chance of encountering a buffer underrun. The software
will always try to find the lowest read speed and set the write speed accordingly.
If you are using extremely poor quality CD-R discs as a destination, or if the Auto
speed setting failed and created a bad copy, you may need to use a manual setting for
Speed. The 1X speed setting will give the best chance to make a clean copy, but will
take the most time.
